This problem occurs even on new devices. iPhone 15 Pro And iPhone 14 — the settings may be to blame iOS, as well as mobile operator restrictions. In this article, we'll look at all possible reasons, including hidden carrier restrictions and firmware bugs that Apple hasn't yet fixed in iOS 17.4.

First, check the obvious: is mobile data turned on? Settings → Cellular) and whether your plan's traffic limit has been exceeded. If everything is fine, but sharing still isn't working, read on. We've compiled solutions for all versions. iOS (from 15 to 17) and models iPhone (from SE 2020 to 15 Plus).

Important: Some issues are related to operator policy (For example, MTS or Beeline may block data sharing on certain plans). If none of these methods help, contact your operator's support team and ask them to check your settings. APN.

1. The access point does not turn on: the switch is grayed out in the settings

If on the menu Settings → Tethering switch "Allow others" inactive (gray), the problem lies in one of three places:

• 📱 No SIM card or it is not recognized (check the tray and contacts).
• 📡 There is no cellular network signal (there is no indicator in the status bar 4G/5G).
• 🔒 The operator has blocked the function (relevant for corporate tariffs or old SIM cards).

Please reboot first iPhone — sometimes this clears temporary modem glitches. If that doesn't help:

1. Open Settings → Cellular → Data Options → Cellular Data Network.
2. Check if the fields are filled in APN, Username And Password (if not, request the data from the operator).
3. Make sure that in the section Settings → General → Software Update the latest version is installed iOS.

2. Devices don't see the iPhone's Wi-Fi network

If the access point is turned on, but other gadgets (laptop, Android-smartphone, iPad) do not find it in the list of networks, the problem may be in:

• 🔄 Wi-Fi channel conflict (iPhone automatically selects a channel that may be occupied by other networks.)
• 🔐 Hidden network (the "Hide network" mode is enabled in the modem settings).
• 📵 Wi-Fi module hardware failure (rare, but occurs after falls or exposure to moisture).

First, try changing the Wi-Fi channel manually:

1. Go to Settings → Personal Hotspot → Wi-Fi Password.
2. Click on the field Network name and add the symbol at the end _5G (For example, iPhone_5G). This will make iPhone use the 5 GHz band, which is less susceptible to interference.
3. Reboot iPhone and try connecting again.

If that doesn't help, reset your network settings:

Settings → General → Transfer or reset iPhone → Reset → Reset Network Settings

3. There is a connection, but the Internet doesn't work.

Situation: The device connects to an access point iPhone, but the pages aren't loading, and there's an exclamation mark next to the Wi-Fi indicator. Reasons:

• 🌐 No mobile internet (check your balance, traffic limit or coverage area).
• 🔌 IP addresses are not issued (malfunction DHCP-servers on iPhone).
• 🛡️ Traffic blocking by the operator (for example, for VPN or torrents).

The first thing to do is turn modem mode on and off (drag the slider to Settings → Tethering). If it doesn't help:

1. Open on a connected device (e.g. laptop) Command line and run:

   ping 8.8.8.8

   If the ping works, but websites don't open, the problem is DNS. Write it manually 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).

2. Check if it is turned on iPhone mode Saving traffic (Settings → Cellular → Data Options).

What to do if there is no ping?

• 🚫 The access point turns on, but no traffic is transmitted.
• 💰 Money is written off for distribution (even if the tariff is "unlimited").
• ⚡ A sharp drop in speed after connecting a second device.

How to check:

1. Open your operator's personal account (via the website or app) and find the "Services" or "Additional Options" section.
2. Call the hotline and ask: Is tethering allowed on my plan?
3. Try inserting the SIM card into another phone (Android) and turn on the distribution there - if it doesn’t work, it’s the operator’s fault.

Some operators only allow data sharing after a paid option has been activated. For example, Beeline This is the "Modem" service, MegaFon — "Internet for devices." Cost: 50 to 200 rubles per month.

6. Problems after updating iOS

Updates iOS often bring new bugs, especially in modem operation. For example, after the release iOS 17.2 many users iPhone 13/14 Complained about the distribution shutting off spontaneously. What to do:

• 🔄 Rollback to a previous version (possible within 2 weeks after update).
• 📡 Reset network settings (see section 2).
• 🛠️ Installing the iOS beta version (if the bug has already been fixed in the test build).

How to roll back to an older version iOS:

1. Download the firmware file (.ipsw) for your model from the website ipsw.me.
2. Connect iPhone To Mac or PC with installed iTunes (or Finder on macOS Catalina and newer).
3. Clamp Shift (Windows) or Option (Mac) and click Restore iPhone, then select the downloaded file.

FAQ: Frequently asked questions about sharing Wi-Fi from your iPhone

Is it possible to share Wi-Fi from an iPhone without a SIM card?

No, to share your mobile internet, you need an active SIM card with a data plan. However, you can share your internet by connecting to another Wi-Fi network (for example, at a cafe) and enabling "Tethering" mode. iPhone will rebroadcast someone else's Wi-Fi.

Why does my iPhone share the Internet, but the speed is very slow?

The reasons may be different:

• The operator throttles the speed after high-speed traffic is exhausted.
• Weak cellular network signal (check the number of bars in the status bar).
• The update is running in the background iOS or backup to iCloud.
• iPhone overheats and reduces the modem's performance.

Try disabling background tasks (Settings → General → Software Update) and reboot your phone.

How to change the hotspot password on iPhone?

Go to Settings → Personal Hotspot → Wi-Fi Password and enter a new password (at least 8 characters). We recommend using a combination of letters, numbers, and symbols (e.g., iPh0n3_Mod3m_2026!). After changing the password, all connected devices will be disconnected.

Is it possible to share Wi-Fi from an iPhone to multiple devices at the same time?

Yes, iPhone supports connection up to 10 devices at the same time (depending on the model and version iOS). However, the more connections you have, the more the speed drops and the faster the battery drains. For stable operation, we recommend limiting the connection to 2-3 devices.

Why did the "Personal Hotspot" option disappear from Settings after updating iOS?

This may be due to:

• Parental control restrictions (Settings → Screen Time).
• Malfunction iOS (resetting all settings will help).
• Incompatibility with the operator (for example, on some corporate SIM cards the function is disabled at the firmware level).

Try updating iOS to the latest version or contact support Apple.
